Police found the brother of convicted child-killer Levi Aron dead in his Kensington home Friday afternoon, authorities say.

They say they found 29-year-old Tzvi Aron's body in the same house they once found the remains of a missing 8-year-old boy, Leiby Kletzky. Aron was found wrapped in a blanket and duct tape.

Investigators did not immediately identify a cause of death. The city medical examiner removed the body Friday evening for further investigation.

As News 12 has reported, Levi Aron was convicted of kidnapping and killing Leiby in 2011. He is serving a sentence of 40 years to life in prison.

Leiby's disappearance kicked off a massive search, and authorities eventually found his remains in a freezer in the Kensington home.
